Technical Field

[0001] This utility model relates to the field of heavy metal simulation testing technology, and in particular to a device for preparing biomass models of heavy metal pollutants. Background Technology

[0002] Studying the migration and transformation of heavy metals in biomass through simulated preparation devices can provide a better understanding of their environmental behavior and offer a scientific basis for pollution assessment and risk management. It can also be used to test and optimize various remediation technologies, such as electrokinetic remediation, phytoremediation, microbial remediation, and chemical stabilization. Existing preparation devices achieve simulation and preparation requirements by incorporating sprayers and filter plates inside the device; however, these devices cannot agitate the biomass to ensure uniform rinsing. Furthermore, after preparation, the biomass easily clogs the device's drain pipe, making cleaning difficult. Summary of the Invention
